Lab 5 Description

In this lab we will test the following commands: apt-get update, ping, netstat, wget, locate, gzip, gunzip, tar, zip, and unzip.

Command apt-get update:

The following command allows the user to update the system packages by looking in the Linux repository. This command is similar to an update in windows. In the following we try to update the the system but access is denied because we do not have administrator access or root access.

Command gzip:

The following command allows the user to compress one or more file. In the following case the foo.txt is created and then using the gzip command is compressed.

Command gunzip:

The following command allows for the user to decompress a file. In the following case the foo.txt that was compressed is decompressed back into a text file.

Command tar:

The following command allows the user to archive files. In the following case the desktop directory is archived. Then to retrieve the stored information using the tar xvf desktop.tar command

Command zip:

The following command allows the user to compress and archive files. This tool combines both the gzip and tar command into one function. In the following case foo.txt and input_file.txt are compressed and archived into the text.zip.

Command unzip:

The following command allows the user to decompress and retrieve the file that are stored in the zip file. In the following case the text.zip file is decompressed and then the two text files are retrieved from within.
